UMBRELLA AND PARASOL.

SPECIFICATION forming part of Letters Patent No. 341,862, dated May 11,18186.

(No model.)

To all whom it may concern:

Be it known that I, ARTHUR SYDENHAM, of Nebraska City, in the county ofOtoe, in the State of Nebraska, have invented a new and usefulImprovement in Umbrellas and Parasols, which improvement is fully setforth in the following specification, reference being had to theaccompanying drawings.

This invention relates to improvements in umbrella and parasol frames;and it consists in improving the runner and fixed ring,

and also the ribs and theirjoint-connections, as will be fullyunderstood from the following description, when taken in connection withthe annexed drawings, in which- Figure 1 is a view of a portion of anumbrellastick having myimprovements applied to it. Fig. 2 is aperspective view of the improved runner. Fig. 3 is a similar view of thefixed connecting-ring. Fig. 4 is aview of one of the ribs, showing itsbroad coiled eyebearing. Fig. 5 is a detail of the same. Fig. (5 is acentral section through the runner enlarged.

Referring to the annexed drawings by letters, A designates part of theumbrellastick, and B the fixed ring, having its sleeve secured in asuitable manner to the stick near one extremity, and connected to. itare the upper hooked ends of the ribs E, as shown in Fig. 1. The hookedends of the ribs are first formed by spreading the metal and bending itso as to leave broad fiat hooks, which are passed through apertures inthe web of the fixed ring B, and then firmly closed, thus formingarticulating fastenings, which will not rock or twist laterally.

About midway ot the length of the ribs E, I form eyes, b, by coiling therib several times and thereby forming broad eye-bearings andjoint-connections for the hooks b on the outer ends of the braces C. Bythus connecting the in the web of the runner-D, asshown in Fig. 1.

It is well known that hitherto the joints forming the connectionsbetween the ribs and fixed ring and the braces and runner of an umbrellaare the weakest points and first to give way. To overcome this objectionby a cheap and simple means is the main object of my invention.

The fixed ring B and the runner D are, or may be, constructed exactlyalike. Therefore a description of one will give a clear understanding ofthe other. I take a fiat ring, and by suitable means I l'orm notches inits periphery equidistant from each other, leaving intermediate tonguesor divisions, c, which have grooved seatsf in their ends. I then preparea ring, g, of suitable diameter and gage of round wire to afford therequisite strength. This ring is fitted into the grooves or seats f, inthe ends of the divisions e, and permanently fixed thereto by soldering,brazing, or otherwise casting it and the flat notched ring together. Bythese means I re-enforce the periphery of the fixed ring and the runner,and form round bearings'for the broad flat hooks on the ribs and braces,and thus afford very strong and durable connections at these joints.

I am aware thatit is not new in umbrellaframes to form ribs withintegral eyes to receive the outer ends of the braces, nor is it broadlynew to form a runner and a fixed ring with an annular series ofapertures to receive the hooked ends of the braces and ribs. I thereforedo not claim either of these constructions, broadly; but

\Vhat I do claim is 1. An umbrella brace or rib attachment consisting ofa flat ring having notches in its periphery, leaving tongues ordivisions 0, pro vided with grooved seats in their ends, in combinationwith a re-enforcing ring secured in said seats, substantially as and forthe purposes described.

2. Au umbrella-frame consisting of a staff, A, the runner, and fixedcrown-piece, each having a ring secured in seats formed in itsperiphery, divisions e, the ribs E, attached to the ring of thecrown-piece by flat hooks, and having broad eyes b, formed by coilingthe ribs, and the braces 0, connected to said coils and to the ring ofthe runner by broad hooks, substantially in the manner and for thepurposes described.
